LEWIS DOUGLAS YOUNG ATTOR N EYS nited States Patent CATCH FOR ACARDBOARD BOX OR THE LIKE Lewis Douglas Young, Providence, R. 1.,assignor to Douglas Young, Inc., a corporation of Rhode IslandApplication April 23, 1953, Serial No. 350,581

2 Claims. (Cl. 229-47) This invention relates to a catch for securingthe free edges of a hinged box, more particularly a box of some softmaterial such as cardboard, so that the free edges may be released to beswung about their hinge connectlon.

The usual catches which have heretofore been employed for securing thefree edges of a hinged box together comprise a pair of plates which areattached to the front walls of the cover and body sections of the box bypins or rivets which pass through openings in the plates. This requiresconsiderable hand operation and is expensive to assemble in position.

One of the objects of this invention is to provide a catch, each of theparts of which may be secured to the front wall of the box by a singleblow after the parts are placed in the desired position.

Another object of the invention is to provide attaching means which willbe integral and one piece with the plates of the parts which are to beattached so that there need be no separate handling of staples or rivetsfor attaching purposes.

Another object of the invention is to provide an attachment which willbetter secure the plate to the front wall of the box and integrate theplate with the front wall of the box so that the hinged plates may bemade of lighter stock and yet will be sufficiently strong for thepurpose for which they are designed.

Another object of the invention is to provide an attach ing means whichwill have its attachment formed in a plurality of small prongs spreadover a greater area and thus one which will be stronger and yet lessnoticeable on the interior of the box than attachments which haveheretofore been had.

Another object of the invention is to provide the attachment on theinner surface of the front wall of the box which will not protrude intothe box but rather the holding means will be substantially flush withthe inner surface of the front wall of the box to which the catch isattached.

With these and other objects in view, the invention consists of certainnovel features of construction as will be more fully described andparticularly pointed out in the appended claims.

In the accompanying drawings:

Figure l is a perspective view of a box with one form of catch employingthis invention positioned thereon;

Figure 2 is a sectional view on substantially line 2-2 of Figure 1showing a fragmental portion of the box;

Figure 3 is a section on line 33 of Figure 2;

Figure 4 is a perspective view illustrating the inner face of each ofthe catch members prior to their assembly on the box.

in proceeding with this invention, I provide a pair of sheet metalmembers of each catch member by providing an opening with the stockwhich is taken from that opening forming prongs around the edge of theopening, which are of such form and shape that they may be driven into abox of soft material such as cardboard and crimped 2,751,139 PatentedJune 19, 1956 of the box with a single blow and causing theclenchingaction over the back wall of the box as a result of this singleblow.

With reference to the drawings, 10 designates the body section of thebox having a bottom wall 11, an upstanding front wall 12, with acorresponding rear wall and opposite side walls 14. The cover section isdesignated generally 15 and has a top wall 16, front wall 17, with acorresponding rear wall and with opposite side walls 18, all of whichdepend from the top wall 16. These upstanding and depending walls of thetwo sections are hinged together along the abutting edges of the backwalls of the sections in known manner so as to direct the upstanding anddepending edges into abutting relation when the box is closed.

In order to hold this box in closed position, I provide a securing meanswhich I will designate generally 20 and which comprises a pair of catchmembers designated generally 21 on the wall 17 and 22 on the wall 12.Each of these catch members is formed of a plate 23 for the member 21and 24 for the member 22. Each of these plates is provided with aplurality of openings which I will designate 25. These openings aregenerally circular in shape, and from the edge of the opening thereextend a plurality of prongs or projections 26. I have illustrated foursuch projections about each opening in the present illustration althoughthis number may be varied. Each of these projections 26 is of arcuateshape, which stiffens the same materially and permits of the projectionbeing driven through a cardboard wall such as 12 or 17 by a single blowon the plate from which the projection extends. The projections areinclined outwardly from a central axis of the opening perpendicular tothe plate so that when the plate is positioned against the front of thefront wall and struck with a hammer blow to drive the projectionsthrough the wall against an anvil which engages the inner surface of theWall, the tip of the projection 26 will be deflected outwardly as at 27away or outwardly from the center of the opening and thus provide aclinch for securing the plate firmly in position. The tips 27 areembedded in the wall through which they extend so that the inner surfaceof the wall remains substantially flush with no projections beyond it.

The two plates 23 and 24 are equipped with some sort of detachableconnection. Thus, there is a stud 30 provided on the plate 24 extendingoutwardly therefrom, while the plate 23 has a latch 31 hinged thereon bya pintle 32 which extends through eyes 33 on the plate and 34 on themember 31, this latch being provided with a hole 35 which may receivethe stud 30 therein so as to hold the parts in closed position. Theremay be a slight inclination downwardly of the stud 30 so that the partswill have to give some in the initial clasping and will tend to be heldin clasped position after once so positioned.

A paper cover over the wall of the box on both inner and outer surfacesis illustrated although this is not essential.

I claim:

1. In a cardboard box, a body section and a cover section, each havingvertically disposed back and front walls with their edges abutting,means to hinge the back walls together, means for detachably connectingthe front walls comprising a catch member for each front wall, eachhaving a metal plate extending along the outer surface of the front wallonly of each section, each plate having a plurality of holes along itslength with a plurality of integral projections along the edge of eachhole embedded in the front wall over which the plate extends with thefree ends of the projections deflected outwardly in a plurality ofdifferent directions and clinched over the inner surface of the frontwall of the section and firmly securing the plate to the section,detachable connecting means comprising a part carried by one plate and asecond part carried by the other plate, said parts being engageable tohold the pair of sections of the box closed and detachable for openingthe box.

' 2. In a cardboard box as in claim 1 wherein the projections along theedge of each hole are arcuate in cross section.
